high dynamic range

Dynamic range refers to the ratio between the brightest and darkest areas of a scene.

The AR0821 delivers 8.3 MP 4K video at 60 fps with extremely low power consumption, rolling shutter, ON semiconductor‘s exclusive 2.1 µm DR-Pix™ backside-illuminated (BSI) pixel design, and embedded High Dynamic Range (eHDR) ) technology, enabling high quantum efficiency and high dynamic range, delivering superior image quality and advanced features in challenging lighting conditions for applications such as scanners/card readers, machine vision cameras, and more. The AR0821 has been integrated into the Basler dart family of area scan camera modules, enabling a wide range of image processing applications and providing the latest in machine vision technology.

global shutter

Rolling shutters have inconsistent start and end times for each row of exposures, resulting in distortion when photographing moving objects. The global shutter is equivalent to the electronicization of the mechanical shutter. All pixels start exposure at the same time and end exposure at the same time, and there will be no deformation when shooting moving objects. Many industrial application scenarios need to capture images of high-speed moving objects, so most industrial cameras need to use global shutter sensors.

The AR0234CS is available in color and black and white variants with a CRA of 0° or 28°.

near infrared

Near-infrared enhanced (NIR+) products have 3 times higher quantum efficiency (QE) in the near-infrared band than traditional products, which means that under the same noise floor, under the same exposure time and gain, NIR+ products are brighter than traditional products. Conversely, to achieve the same picture brightness, NIR+ products can use less near-infrared illumination, reducing overall power consumption and cost.

RGB-IR

The IR pixels in the array of RGB-IR products adopt the NIR+ IR differential algorithm, which can save the switching of IR cut in traditional industrial cameras, so as to reduce maintenance costs and space occupation. Images captured by RGB-IR processed products show richer and more realistic colors.
